Risperdal Consta belongs to a group of medicines called “antipsychotics”.

Risperdal Consta is used in the maintenance treatment of schizophrenia, which is characterized by seeing, hearing or feeling things that are not present, believing in something that is not true or unusually feeling distrust or confusion.

Risperdal Consta is intended for patients who are currently being treated with oral antipsychotics (e.g., tablets, capsules).

Risperdal Consta may help reduce the symptoms of your illness and prevent them from returning.

No use Risperdal Consta

• If you are allergic to risperidone or any of the other components of this medication (listed in section 6).

Warnings and precautions

• If you have never taken Risperdal in any of its forms, you should start with Risperdal oral before starting with Risperdal Consta.

Consult your doctor or pharmacist before using Risperdal Consta if:

• You have a heart problem, for example, an irregular heart rhythm, or if you are prone to having low blood pressure or if you are using blood pressure medications. Risperdal Consta may lower your blood pressure. Your dose may need to be adjusted
• You know you have a risk factor for having a stroke, such as high blood pressure (hypertension), cardiovascular disorders, or cerebral circulation disorders
• You have ever had involuntary movements of the tongue, mouth, and face
• You have ever had symptoms that include fever, muscle rigidity, sweating, or a decrease in level of consciousness (also known as Neuroleptic Malignant Syndrome)
• You have Parkinson's disease or dementia
• You have had low white blood cell counts in the past (which may or may not have been caused by other medications)
• You are diabetic
• You have epilepsy
• You are a male and have ever had a prolonged or painful erection
• You have difficulty controlling your body temperature or feel excessive heat
• You have kidney problems
• You have liver problems
• You have an abnormally high level of a hormone called prolactin in your blood or if you have a tumor that may be dependent on prolactin
• You or a family member has a history of blood clots, as this medication has been associated with the formation of blood clots.

If you are unsure whether the information above affects you, talk to your doctor or pharmacist before using Risperdal or Risperdal Consta.

Because in very rare cases, a dangerously low number of a type of white blood cell necessary to fight infections in the blood has been observed in patients treated with Risperdal Consta, your doctor may check your white blood cell count.

Rarely, allergic reactions occur after receiving injections of Risperdal Consta, even if you have previously tolerated oral risperidone. Seek medical attention immediately if you experience hives, throat swelling, itching, or breathing difficulties, as these may be symptoms of a severe allergic reaction.

Risperdal Consta may cause you to gain weight. Significant weight gain can negatively affect your health. Your doctor will regularly monitor your weight.

Because diabetes mellitus or worsening of pre-existing diabetes mellitus has been seen in patients taking Risperdal, your doctor should check for signs of elevated blood sugar. In patients with pre-existing diabetes mellitus, blood sugar should be monitored regularly.

Risperdal Consta frequently increases levels of a hormone called "prolactin." This can cause adverse effects such as menstrual disorders or fertility problems in women or breast enlargement in men (see Possible Adverse Effects). If these adverse effects occur, it is recommended that blood prolactin levels be evaluated.

During eye surgery for cataracts, the pupil (the black circle in the middle of the eye) may not dilate as needed. Additionally, the iris (the colored part of the eye) may become flaccid during surgery and this can cause eye damage. If you are planning eye surgery, be sure to inform your ophthalmologist that you are using this medication.

Patients with advanced age and dementia

Risperdal Consta is not used in people with advanced age and dementia.

If you or your caregiver notice a sudden change in your mental state or the sudden appearance of weakness or numbness in the face, arms, or legs, especially on one side, or confused speech, even for a short time, seek medical treatment immediately. This may be a sign of a stroke.

Patients with kidney or liver problems

Although oral risperidone has been studied, Risperdal Consta has not been studied in patients with kidney or liver problems. Risperdal Consta should be administered with caution in this group of patients.

Use of Risperdal Consta with other medications

Inform your doctor or pharmacist if you are using or have used recently or may need to use any other medication.

It is especially important to talk to your doctor or pharmacist if you take any of the following

• Medications that act on the brain used to calm down (benzodiazepines) or some pain medications (opioids), allergy medications (some antihistamines), as risperidone may increase the sedative effect of all these
• Medications capable of modifying the electrical activity of your heart, such as those used for malaria, heart rhythm problems, allergies (antihistamines), some antidepressants, or other medications for mental health problems
• Medications that may cause a decrease in heart rate
• Medications that may cause a decrease in potassium levels in the blood (such as certain diuretics)
• Medications for Parkinson's disease (such as levodopa)
• Medications that increase the activity of the central nervous system (psychoestimulants, such as methylphenidate)
• Medications for the treatment of high blood pressure. Risperdal Consta may lower blood pressure
• Diuretics used for heart problems or to treat swelling in some parts of the body due to fluid retention (such as furosemide or chlorothiazide). Risperdal Consta, taken alone or with furosemide, may increase the risk of stroke or death in elderly patients with dementia.

The following medications may reduce the effect of risperidone

• Rifampicin (a medication used to treat some infections)
• Carbamazepine, phenytoin (medications used to treat epilepsy)
• Phenobarbital.

If you start or stop taking these medications, you may need a different dose of risperidone.

The following medications may increase the effect of risperidone

• Quinidine (a medication used to treat certain types of heart problems)
• Antidepressants such as paroxetine, fluoxetine, tricyclic antidepressants
• Medications known as beta-blockers (used to treat high blood pressure)
• Phenothiazines (such as medications used to treat psychosis or to calm down)
• Cimetidine, ranitidine (medications used to treat stomach acid)
• Itraconazole and ketoconazole (medications used to treat fungal infections)
• Some medications used to treat HIV/AIDS, such as ritonavir
• Verapamil, a medication used to treat high blood pressure and/or abnormal heart rhythm
• Sertraline and fluvoxamine, medications used to treat depression and other psychiatric disorders.

If you start or stop taking these medications, you may need a different dose of risperidone.

If you are unsure whether the information above affects you, talk to your doctor or pharmacist before using Risperdal Consta.

• Risperdal Consta may increase levels of a hormone called "prolactin" that could affect your fertility (see Possible Adverse Effects).

The recommended dose is as follows:

Adults

Initial dose

If your daily dose of oral risperidone (e.g., tablets) was more than 4 milligrams during the past two weeks, you may be given a dose of 37.5 milligrams of Risperdal Consta as the initial dose.

If you are currently being treated with another oral antipsychotic that is not risperidone, your initial dose of Risperdal Consta will depend on your current treatment. Your doctor will choose Risperdal Consta 25 mg or 37.5 mg.

Your doctor will decide if this dose of Risperdal Consta is suitable for you.

Maintenance dose

• The usual dose is an injection of 25 milligrams every two weeks
• A higher dose of 37.5 or 50 mg may be necessary. Your doctor will decide which dose of Risperdal Consta is most suitable for you
